Abstract:
The disclosed invention describes a container end that can be easily opened and does not rely on a conventional metal tab, riveted onto the end, thereby avoiding the problems and the cost associated with such a tab. The invention utilizes a traditional container end shell with a separate and distinct piece that is formed independently and is inserted into a countersink which is placed on the outer surface of the container end shell. The removal of this separate piece exerts a force or causes a change in the properties of the container wall in the countersink area, initiating and proliferating a discontinuity in the container wall, thereby creating an opening in the container. This change in the properties of the container wall can be mechanical, chemical, thermal or any other modality, which has the ability to influence the integrity of the container wall.
Abstract:
A tamper-resistant, tamper-evident composite lid is disclosed for use with containers having a peripheral lip formation around the opening thereof, such as an ice cream container. The closure member comprises integral outer and inner cylindrical ring portions which present at their upper peripheral margin a downwardly stepped annular ledge formation for adhesively receiving a paperboard or other flexible cover panel. The inner ring portion presents a plurality of resiliently deformable teeth extending upwardly and inwardly from its lower peripheral margin configured to lockingly engage with the lip of the container for sealing. The inner ring is circumscribed by a rupturable line of weakness which ruptures upon any attempt to prise off the lid, providing evidence of tampering. The container is legitimately opened by manually tearing away the bottom portion of the inner ring along its line of weakness.
Abstract:
A plastic lid for a pail. The lid has an edge section that extends exterior to the pail, one section of the edge section forming a hinge section. The remainder of the edge section has three sections. Each of the sections extends peripherally around the edge of the lid. One section, intermediate between the other sections is integrally formed with the other sections, and tearable therefrom. The hinge section being integral with one section and has a portion of reduced thickness juxtaposed to the rim of the container. The lid is rotatable about the hinge for opening of the pail after removal of the tearable section. The lid and pail are tamper-evident, and the lid is retained on the pail after opening.
Abstract:
An easy-opening can end and tools for making the same in which the can end is intended for cans of food products or other non-pourable products in which the can end has an improved pull tab attached to a relatively large removable panel portion and in which the tab has a bending fulcrum behind the rivet to facilitate severance of the score around the removable panel. The tab has a C-shaped slot in it around the side of the rivet toward the center of the can end to permit limited bending of the tab along the fulcrum line.
Abstract:
The invention concerns a cylindrical cartridge (1) made of moulded material for use in a grease dispenser, closed on one side with a cap and the other with a frangible lid (2), characterized in that the lid (2) shaped like a disc (4) enclosed with a skirt (5) extending thereabove, over a constant height h, is secured to the end of the cartridge by a tearaway film (6) linking it to the outer edge (5a) of the skirt (5) which comprises a cut (7) over its length extending on the disc to form a radial cutout (8) whereof the outer edges support two equal vertical flanks (9), arranged facing each other, secured to the sides of the cutout (7) edges and linked at their free edges by a tearaway film (10) providing the lid with tightness, a thread (11) emerging from the flanks (9) to form the pull-ring.
Abstract:
A combination molded plastic bucket and lid includes a series of outwardly extending ribs on the top edge of the bucket and inwardly extending flanges on a depending outer skirt of the lid which engage with the bucket ribs to provide a wedging action that holds the lid tightly in a sealing position on the top of the bucket. A zig-zag tear strip permits removal of a portion of the lower most lid flange. The top of the bucket includes a groove adapted to receive a projection or tongue seal.

Abstract:
A tamper proof ABS plastic container comprising a container body within which medical or hygiene products such as capsules or tablets can be accommodated, the container body including a base section (1) and a lid section (3) of an intermediate section (7) and cover (5) with cooperating coupling means (17) to engage with the intermediate section (7); a tamper prevention means (9) interconnecting the base and lid sections of the container body, the tamper prevention means including a web section (11) located between and secured to both the base and lid sections, and a hanging pull tab (13); wherein the web section is detachable from the container, the detaching of the web section allowing separation of the base and lid sections of the container body and visual indication that the container has been opened, Also provided is a method of injection molding of the base section, web section and intermediate section as an integral unit.
Abstract:
A tubular paperboard container having a tear-strip opening and reclosure feature. A lid is insertably received in an open top end of a tubular body portion, with an upturned edge region of the lid being flush against an inner surface of the tubular body portion. Removal of the tear strip exposes a downwardly extending portion of the lid that is insertably receivable, in a plug-like manner, in the remaining, now-open top end of the tubular body portion.
Abstract:
A closure (3) for a container (1), the container having a mouth (16) surrounded by an external flange (7) extending generally away from the mouth, the closure comprising a closure body (9) adapted to extend across the mouth, a skirt (15) which is disposed below the level of the container flange when the closure is initially secured to the container and the mouth is uppermost, the skirt being connected to the margin of the body by a plurality of spaced-apart bridges (19) which lie adjacent to the outer margin of the flange in the initially secured condition of the A closure, and a plurality of upwardly-facing latching formations (20) depending from the skirt (15) and each disposed circumferentially between adjacent bridges (19) as viewed in plan and adapted to latch under the flange (7), the upper portion (23) of the latching formations each lying vertically beneath a respective tool access aperture (25) provided in the margin of the closure body. The tool access apertures (25) enable the closure to be thermo-formed from sheet plastics material on a two-part tool assembly. Two configurations of latching formation (20) are described. In one construction, FIGS. 1 to 7, each latching formation comprises a latch wall (21) of trapezoidal shape supported on the skirt in an inclined position by a pair of substantially triangular fillets (22). In a second configuration, FIGS. 8 to 13, each latching formation is defined by a pair of triangular latch walls (22null) having a common edge (21null)which is inclined inwardly and upwardly of the closure.
